ANTIRATTLER FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 573,786, dated December22, 1896.

Application filed April 29, 1896. Serial No. 589,600. (No model.)

To @ZZ whom, it may concern:

Beit known that LHERBERT W LAWRENCE, of Montevideo, Chippewa county,Minnesota, have invented certain new and useful Improvements inAntirattlers for Thill-Oouplings, of which the following' is aspecification.

The object of this invention is to provide an improved device that maybe quickly and readily applied to any form of vcarriage, for the purposeof forming an antirattler for the thills, and also for forming a lockfor the nut or bur on the bolt that secures the thill in position.

Theinvention consists generallyin the constructions and combinationshereinafter described, and particularly pointed out in the claims.

In the accompanying drawings', forming part of this specification,Figure 1 is a section of a carriage-axle, showing a portion of the thilland the thill-coupling with my antirattler applied thereto. Fig. 2 is aplan View of the same. Fig. 3 is a section on the line a: .oc of Fig. 2.Fig. i is a perspective view showing the antirattler-clip detached.

In the drawings, 2 represents the clip, that is secured to the axle inthe ordinary manner and to which the thill-iron 3 is secured by means ofthe bolt 5. These parts are all of ordinary construction.

My antirattler-clip consists, preferably, of a single piece of sheetmetal having the rear depen ding portion 7, that is adapted to extenddown between the two projecting portions of the coupling-clip in therear of the curvedl part of the thill-iron. The front part of this clipis provided with the two strips 9, that bear upon the forward ends ofthe couplingclip 2. The space between these two strips is open to permitthe passage and the free movement of the thill-iron. At the lower endsof these strips is the plate 11, and a bolt 13 passes from the rearthrough the plate 7 and through the plate 1l and is provided upon itsend with the nut or bur 15. A rubber or other spring washer 17 isarranged upon the bolt between the plate 11 and the nut l5. A metallicwasher 18 is also preferably arranged between said nut 15 and thespring-washer 17. I prefer also to provide a leather wearin@P late orstri 2O which is arranged be- D p 7 b tween the plate 7 and the end ofthe thi1l iron. The plate 11 is also preferably provided at its end withthe inturned projection 2l, having the lip 22 at its upper edge, andupon this lip the nut- 8 of the coupling-bolt 5 rests when the bolt isin place.

In coupling the device the nut is put in position first and the bolt 5is screwed into place through the nut. The lip 22 on the projection 2lholds the nut from turning and per-v mits the bolt to be inserted orremoved by the use of a single wrench. It will be seen that the devicemay be readily attached to any thill-coupling. It may be quickly put inposition or removed and does not interfere with the free movement of thethills. The leather 2O may be renewed whenever it becomes worn and thisis the only part `of the device upon which there will be any appreciablewear.

As the strips 9 rest upon the ends of the coupling-clip 2 they arerigidly supported, and by tightening the nut l5 upon the bolt 13 theplate 7 may be drawn against the rear end of the thill-iron with anydesired pressure, so as to force the thill-iron forward and hold itclosely against the rear side of the bolt 5. This prevents any rattlingof the thilliron upon the bolt 5 and also prevents any rattling of thebolt 5 in the coupling-clip.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. As an article of manufacture, the hereindescribedantirattling clip, consisting of the plate 7, the curved forward strips9 and the plate 11, with the bolt 13 extending through the lower part ofthe plate 7 and through the plate 11, and provided with the nut 15 andspring-washer 17, for the purpose set forth.

2. As an article of manufacture, the hereindescribed antirattlin g clip,consisting of a rear curved plate, curved strips extending forward fromthe opposite ends of said plate, a plate uniting the ends of said curvedstrips, and a bolt joining said plates and provided With a suitable nutand with a spring-washer, for the purpose set forth.

3. As an article of manufacture, the antirattling clip comprising theplate 7, the curved strips 9 extending forward from the upper edge ofvsaid plate, ythe plate 11 joining the IOO forward ends of said strips9, and the projection 2l upon the plate 11 provided with the lip 22, forthepurpose set forth.

4. The Combination, with the coupling-clip, the thill-iron, thecoupling-bolt and its nut, of the antirattling clip Comprising vtheplate 7, extending between the parts of the coupling-clip, the stripsextending` from the npper forward edge of said plate 7 and bearing` uponthe forward ends of the coupling-clip, the plate 11 joining the lowerends of said strips, the leather plate 20 arranged between saidthill-iron and said plate 7 and the bolt 13 passing through said plates7 and 11 and provided with the spring-Washer 17 and the 15 nut 15, forthe purpose specified.

In testimony whereof I have hereunto set my hand this 22d day of April,A. D. 1896. HERBERT IV. LAVRENCE. In presence of B. O. PICKLE, ETTA L.GRAHAM.
